Probably Something Stupid on My Part

Ok...should I have to do anything more to see the sample app from Git than put it in a directory up on a standard LAMP build and hit its index file?

I threw this up on a server, and get this error:

Error: The following classes are not declared even if their files have been loaded: 'Sencha.ux.SignaturePad'. Please check the source code of their corresponding files for possible typos: 'app/plugin/SignaturePad.js
[Break On This Error]

Create a loader in Application
Add in routes this:
{'Ext.ux.touch' : 'app/ux'}
or if you wanna be more specific:
{'Ext.ux.touch.Rating' : 'app/view/fieldRating.js'} //this uses starRating, renames and relocates in another place

and you can load this, but you can't edit in SA, you need external editor to edit anything inside the file, as an extra thing, don't forget to use require in the Class that is invoking it.
